* Tests must be conducted within 10 m of the infiltration practice footprint area.
* Tests must be conducted within 10 metres of the infiltration practice footprint area.
* Tests should be performed within 48 hours of a rain event, when the soil is already near or at field capacity.

* An additional round of tests should be conducted at 1.5 metres depth below the proposed bottom elevation of the practice if there is significant variation in geologic formation, soil texture or bulk density compared to conditions at the proposed bottom elevation.<br>

* To calculate the median infiltration rate of the native soil at the depth tested, discard the highest and lowest values obtained from each test location and calculate the median from the remaining measurements at the depth tested.
